so if u could help me find the right caliber that i should be shooting at 1000 yards
Chuck,
It seems like you want someone to just give you a turn-key one-size-fits-all answer.(Hard to tell, really. Try using normal capitalization, punctuation, etc. to help us understand you better) The problem is, and I believe Charles already pointed out, what is 'best' for one particular competitive venue is not necessarily even legal for use in another. If you want to compete in no-holds-barred 1k yard benchrest competition, then the whole landscape of what is popular and winning matches is very different than what would be appropriate if you are looking at say, Palma or F-Class. The rules for each sport are different, and the calibers allowed are different.
If you are just starting out, which it sounds like you are, my advice is simple: Go watch some matches first, or at least take a look on-line at the various competition types and get some idea what you want to do *first* before making any decisions or spending any money. Tell us where you are located (usually a good idea to be courteous and fill out that part of your user profile on any forum so people have some idea what locale you are in to begin with) and someone can probably point you in the right direction to find different kinds of matches in your area. You might even get lucky and be able to hook up with someone who might help you out and maybe let you try their rifle out.
If you aren't willing to do that... my advice would be to get a .308 Winchester. Probably a Savage
Reason being that if you don't handload, you can still buy ammunition that will shoot acceptably at distance (bearing in mind that 'acceptably' has a wide variety of interpretations). As you do start handloading, the .308 is pretty well mapped out - and very easy to get to shoot well, despite any initial blunders a new reloader may make (and we all have). The barrel will last a good long while (3000rds minimum, more like 4-5k +) so you can spend more time shooting and less time worrying about whether your barrel is going south on you. Once you've been shooting that a while, you'll hopefully be better able to define what it is you want to do - and with any luck along the way, you might even learn a thing or two about wind reading
If you were intending on getting straight into competitive Benchrest or other forms of long-range competition, my answer might be somewhat different. As it is... it sounds like you need to figure out what you want to do first, and even then, you can't go very far wrong with a .308 Winchester of some sort in the gun safe
